# This set up both the can0 and can1 interfaces. We have Waveshare CAN transcievers connected to the bus on both can0 and can1.
# We can ONLY see packets arriving on can0.
# We run:
#     candump -t a can0
# And can see heartbeats print out from both motor controllers.
# We run:
#     cansend can0 123#abcdabcd
# And we can see this sent message in our running candump.
#
# Multiple times we ran:
#     sudo reboot
# Then logged back into the jetson over ssh, and ran:
#     ./working_CAN_setup_3_7_19_v1.sh
# And tested candump and cansend immediately afterwards and they work.
